Product Description
Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warm extruded and welded by automatic double wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel to the welding pipe unit, and the strip steel is rolled by multiple rolls. The strip steel is gradually rolled up to form a circular tube blank with an open gap. Adjust the reduction of the extrusion roll to control the weld gap at 1~3mm, and make both ends of the weld crater flush.
Spiral welded pipe
Compared with the straight seam welded pipe, the spiral welded pipe has higher strength and larger diameter. The production standard of the spiral welded pipe is more than that of the straight seam welded pipe. Mainly used in steel structure engineering, machinery manufacturing, construction water, oil pipelines and other low-pressure fluid pipelines, and can also be used in piling, structure and other construction fields

Spiral Welded Steel Pipe Production Process
The production of spiral welded steel pipes can reflect the advantages of high quality and high efficiency. The production capacity of one spiral welded pipe unit is equivalent to 5-8 sets of straight seam welded pipe equipment. How to make multiple pipe coiling equipment production lines meet the same production standard, that is, produce according to a unified production process specification and quality assurance system to meet welding quality Requirements and piping manufacturing grades will be an arduous task.
Advantages of spiral welded pipe:
(2) Under the same pressure conditions, the stress of the spiral welded seam is smaller than that of the straight seam, which is 75% to 90% of that of the straight seam welded pipe, so it can withstand greater pressure. Compared with the straight seam welded pipe of the same outer diameter, the wall thickness can be reduced by 10% to 25% under the same pressure.
(3) The size is accurate, the general diameter tolerance does not exceed 0.12%, the deflection is less than 1/2000, and the ovality is less than 1%. Generally, the sizing and straightening process can be omitted.
(4) Continuous production is possible. In theory, long steel pipes can be produced, with small head and tail loss, and can increase the metal utilization rate by 6% to 8%.
(5) The equipment is light in weight and low initial investment. It can be made into a trailer-type mobile unit to directly produce welded pipes at the construction site where the pipeline is laid.
Spiral Steel Pipe Usage:
1) Liquid transport
2) Chemicals, natural gas transportation
3) Used in the piling pipe,construction pipe
4) Agricultural irigation, urban construction
